ive had that heppen many times...dont water it to tryna get it to come off.  what i do is take my lil eye dropper an apply one or two drops of water right onto the husk,,helps to soften it up sometimes..i do that maybe twice over a coupke days an then  take a pointed tooth pick and gently hold the seedling with a couple fingers and gently use the tooth pick to tryna pry off the husk..usually werks..be gentle
